CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 655,247, dated August7, 1900.

Applloation filed April 10, 1900. Serial No. 1.21343. (No model.)

To all whom it may concern: I

Be it known that we, J 6RGEN KLGVSTAD, carriage manufacturer, and GUSTAVWIL- HELM JONSEN, carriagesmith, citizens of the Kingdom ofNorway,residing at 39 Hoellergaden, Christiania, Norway, have invented certainnew and useful Improvements in Carriages or Vehicles; and We do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

In the carriages or vehicles which are at present most generally in usethe front axle is provided with two springs mounted upon the fifth-wheellengthwise "of the carriage. The arrangement known from Americanconstructions and having only one spring situated opposite the frontaxle transversely to the carriage provides not only a nicer appearanceof the vehicle, but also enables to considerably to reduce the weight,and besides possesses the advantage of having the spring rigidlyattached to the body of the carriage and not, as usually, to the axle.When, however, said arrangement has not come into common use, this issubstantially due to the fact that in the general form of carrying outthe same it will impair to a considerable degree the swinging of thefront wheels, (allowing only of half a turn,) this involvingdifficulties in the use of such carriages when turning with the same innarrow passages.

The object of the present invention is to with each other by a kind oftoggle-joints and journaled lengthwise of the vehicle, one underneaththe bottom of the same and the other on the fifth-wheel.

The accompanying drawing illustrates an arrangement embodying thepresent invention.

The carriage-spring a is attached trans versely, as shown, to across-piece mounted upon the fifth-wheel c. Projecting upward from thelatter are lugs or journal-bearings d e, carrying boltsfg, that form oneof the axles of the toggle-joint, while the other is formed by similarbolts h 1;, inserted into pendent brackets 70 Z, secured to the bottomof the carriage. A double lever consisting of parallel arms mn,connected by the cross-bar o, is suspended upon the upper bolts andjointed by bolts p q to a similar double lever pivoted on the lower axleand comprising arms 7" 8, connected by a cross-bar t. The several boltsare made of a sufficient length and may, if desired, be extended, so asto form continuous axles. The bolts are preferably made of a taperingform, so as to be capable of being tightened when worn away in order toobviate jolting of the carriage. A mechanism of this description willallow of free movement vertically without causing undue friction and atthe same time precludes any angular movement of one of the toggle-jointsrelatively to the other, and consequently secures against any yieldingof the carriage-frame in the longitudinal direction. Such arrangement ofthe frame secures a reduction in weight by forty to fifty kilograms. Theplacing of the spring upon the body of the carriage, furthermore,involves the advantage that damages caused by collisions or otheraccidents will be more easily and cheaply repairable, the frame, whichwill more particularly be liable to receive such damages, comprising inthis case only the axle and the lower fifth-wheel.
